ERIC W. PALMQUIST, OF CHICAGO, ILLINOIS, ASSIGNOR TO'AMERICAN STEEL FOUNDRIES, OF CHICAGO, ILLINOIS A CORPORATION OF NEW JERSEY.

BRAKE-HANGER- EQUIPMENT.

To all whom it may concern:

Be it known that I, Earo W. PALM msT,

a citizen of the United States, residing at be readily applied to its support, moved into arrangement shown in Fig. 2.

a locking position with respect thereto, and

readily removed therefrom.

- The invention is illustrated on the accompanying sheet of drawings, in which Figure 1 is a fragmentary side elevation of a railway car truck embodying my invention;

Fig. 2 is a sectional view taken through the car truck and showing the manner of applying the brake hanger to its sup ort, alsg showing the novel supporting mem er; an

Fig. 3 is a fragmentary plan View ofthe The truck side frame 10 is provided with a laterally extending support 11, in which a brake hanger 12 is mounted, the lower end of the brake hanger being connected to a brake head ,13 carrying a brake shoe 1% arranged to cooperate with an associated truck wheel 15.

The outer end of the bracket or support 11 is provided with spaced upper and lower jaw members 16 and 17 at the rear end of which is provided a transversely extending horizontal bearing portion 18 for the reception of the upper portion 19 of the closed loop hanger 12. The jaws 16 and 17 proper are skewed into a position wherein the same are arranged at substantially an angle of 45 with respect to the bearing portion 1-8, or with respect to the horizontal and extend entirely across the jaw portion of the support in the same direction. These spaced and skewed jaws 16 and 17 thereby form an opening therebetween, which also 1s at an angle with respect to the bearing portion 18. It is apparent, therefore, that in order to apply the link hanger, the latter must be moved into an angular position so that its upper portion 19 coincides with the angle of the skewed jaws, whereupon said Specification of Letters Patent. Patented Dgc. 2 1919.

portion 19 may slide through the opening between the jaws and downwardly through sald opening into the horizontally arranged bearing portion 18. In order to withdraw the link brake hanger it is nec essary for it to take a reverse movement. However, when the linkis applied to the brake head behind the brake shoe, it is im possible for the hanger to move into an an.- gular position permitting the removal of the hanger. Accordingly, when the hanger is in the position shown in the figures of the drawings, it is locked, thereby preventing the hanger from becoming disengaged from its support and thereby preventing the hanger, brake beam, head and shoe from fallingvto the track and causing a wreck.

his a simple matter to apply this hanger,

it not being necessary to remove the wheels from the truck. It is simply necessary to turn the hanger 12 at an angle while still maintaining it in a vertical plane intermediate the truck side frame bolster leg and the wheel, whereupon the upper portion 19 of the hanger will be received between the skewed jaw members 16 and 17 and set into place in the bearing portion 18.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

I claim: 1. In brake mechanism,-the combinatio of a support having skewed jaws extending entirely across the jaw portion of said support in the same direction, and a hanger applied to said support between said skewed aws.

2. In brake mechanism, the combination of a support having a bearing portion and skewed jaws arranged at an angle with respect thereto, and extending entirely across the jaw portion of said support in the same direction, and a brake hanger which may be.

passed between said skewed jaws into said bearing portion wherein the hanger is lacked.

3. In brake mechanism, a truck side frame having a. supporting portion with a bearing therein and skewed aws, which extend in the same direction throughout their length, and a brake hanger insertible between said jaws and normally located in said bearing portion.
